- Cuba 🇨🇺 has just recorded its lowest temperature on record this morning, with 0.0°C (32°F) at Indio Hatuey. This marks the first time in recorded history that the country has reached the freezing point.
- The hydrological situation across a large part of the Iberian Peninsula is alarming, to say the least, and conditions are set to worsen as several powerful atmospheric rivers are forecast; major flooding cannot be ruled out.
- Portugal and Spain are looking at tremendous precipitation from an onslaught of atmospheric rivers over the next 14-days. Flooding will certainly be a very real threat if these numbers materialize.
- Storm Harry poses an extremely dangerous flooding threat to the central Mediterranean. The most extreme rainfall is forecast over eastern Sicily, especially the Province of Catania, where more than 500 mm of rain may fall in less than 48 hours.
- Chilling satellite imagery emerging as #StormGoretti unleashes full fury upon parts of the UK and France. A 213 km/h wind gust was just reported at Gatteville-le-Phare (Manche) in northwestern France.
- The latest high-resolution Met Office UKV model remains particularly aggressive regarding the impacts of Storm Goretti (named by Météo-France), with gusts of up to ~200 km/h modeled in the English Channel.
- Gorgeous satellite view of the fresh snow cover across northwestern France🇫🇷
- I can’t recall ever seeing a fog event footprint show up so clearly on a 30-day temperature anomaly map. Absolutely fascinating. California’s Central Valley really sticks out amid widespread warmth across the West.
- It's hard to grasp the immense scale of the Indonesia floods until you see it from space. And this is just a fraction of the full extent.

- A big change of air mass is on the way.
- This has to be unheard of. With an extraordinary peak flash rate of 699 flashes per minute just prior to landfall in Jamaica, Melissa probably set the record for the most prolific inner-core lightning outbreak ever recorded in an Atlantic hurricane.
- This is wild. Despite having fueled one of the strongest Atlantic hurricanes on record, the waters in the vicinity of where Melissa tracked remain sufficiently warm to support the formation of a major hurricane.
- NOAA aerial imagery is coming in. Hurricane Melissa literally turned western Jamaica from green to brown. Vegetation damage is immense — recovery will take years.
- With 40 cm of snow left on the ground last Wednesday, Iceland’s capital, Reykjavík, officially experienced its biggest October snowstorm on record. This historic event shattered a 104-year-old record by 25 cm.
- The fact that we went nearly 20 years without a sub-900 mb Atlantic hurricane and now we’ve had two in just the last two seasons.
- Reposted by Nahel BelgherzeAlrighty, ready to see something really cool? (and maybe a little nauseating) The evolution of Hurricane Melissa's mesovortices at peak strength.
- NEW: Devastating imagery from Jamaica, before & after Category 5 Hurricane Melissa. Black River — near total destruction.
- Hurricane Melissa’s historic journey to becoming one of the most intense tropical cyclones ever recorded on Earth. A storm we won't forget anytime soon.
- Obvious wavenumber-5 mesovortex pattern within #Melissa’s eyewall earlier today — when the simulation matches reality. Just two decades ago, the very existence of mesovortices was still a matter of debate.
- Hurricane Melissa has just broken the record for the driest eye ever observed in a tropical cyclone, with a temperature of -4.75°C. This is nothing short of astronomical.
- The marine heatwave occurring across much of the East China Sea is one of the most extreme ever recorded in this part of the world. Over the past few days, it has reached “Beyond Extreme” Category 5 status — Completely uncharted territory.
- Just a nice calm look at 321 hours out from the GFS.
- Some significant rain totals are possible across parts of the Valencian Community, Spain by the end of the weekend (+350mm). Flash flooding is possible where those biggest totals occur. Red warnings are in force.
- Sunset on Hurricane Humberto. A Category 5 monster.
- This is not normal. Japan is continuing its run of astonishing temperature records. The country has just had its hottest summer for the third year in a row, and by a substantial margin. Data: JMA
- Here’s a 48-hour water vapor loop of Ex-Hurricane Erin spinning on its final approach to Europe. Truly mesmerizing.
- Before-and-after satellite imagery shows multiple large burn scars from the recent major wildfires in Portugal and Spain.
- Here’s a first-of-its-kind vertical cross-section analysis of the eyewall of Category 5 Hurricane Erin, captured by AgileRadar’s ROARS radar system installed on NOAA’s Hurricane Hunters P-3 aircraft.
- Hurricane Erin’s substantial wind-field expansion over the past four days.
- Spain is having its worst year for wildfires. In terms of square kilometers burned, the 2025 season far outstrips all previous years. Many fires are still active.
- Unbelievable footage from NOAA’s Hurricane Hunters inside the eye of Hurricane Erin. Simply incredible.
- Just dreadful satellite imagery of the rapidly escalating wildfire outbreak across parts of northern Portugal and western Spain. Look at the size of that smoke plume!
- Historic heatwave unfolding in France. Bordeaux just observed its hottest day on record with a provisional 41.6°C (107°F) — data since 1920. Red level extreme heat warnings are in force for the south of the country. Sadly, this heatwave is far from over...
- The ongoing, potentially record-breaking heatwave in southern France could last longer than previously thought, according to the latest ECMWF ensemble.
- From record-breaking warmth to slightly below-average sea surface temperatures, this map highlights the remarkable cool-down that occurred in just one month in the western Mediterranean Sea. *Internal variability*
- This is unbelievable. The high temperature at one of Finland’s northernmost weather stations, in the municipality of Sodankylä (Lapland region) within the Arctic Circle at latitude 67.3°N, reached at least 25°C for 26 days in a row. Records date back to 1908.
- We just witnessed Japan's hottest day in recorded history again: 41.8°C (107.2°F). The longevity and intensity of this historic heatwave is hard to comprehend.
- Last month was the most anomalous in recorded history for temperatures in Japan. Almost 3°C above the 1991-2020 average. Records date back to 1898.
